Mexico’s former Ambassador to Canada, Francisco Suárez Dávila, says Mexican President Enrique Peña Nieto will likely refuse to attend Justin Trudeau’s proposed North American Leaders' Summit this summer unless the visa requirement on Mexico is revoked — a promise Trudeau and members of his cabinet have reiterated several times since forming government.

“I find it very difficult to concede that President Peña will come to Canada if he has to subject himself to the visa requirement,” Suárez said in an interview from Mexico City, where he retired following the end of his Canadian post in December. “It's a pity because we really could be in the beginning of a golden age of a really grand relationship.”
